As someone who has three, Next Gen TMs are fantastic, truly a joy. They are also a money pit. I went overseas to get work done (Eagle6 in the UK, great folk) because at the time the expertise and parts weren't there in Canada.
For the cost that you would have to drop if you can find one in Canada, plus battery upgrades, plus spring upgrade (most important), plus fixing the absolutely crap battery contacts on the SOPMOD with proper gold connectors... you start to stray (not right in but close) to PTW territory.
